9 Claims.

An object of my invention is to provide an improvement in combination counter top and sink constructions and to particularly provide an improved watertight joint between the two, which is of simple, durable and inexpensive construction.

A further object is to improve the appearance of a counter or table top having a sink countersunk therein by reducing the depth of the usual ofiset around the rim of the sink, which ordinarily is the thickness'of the counter top, 1

whereas in my construction it is possible to pro vide suflioient strength in the counter top and a practical support for the sink, yet provide an apparent offset between the c unter top and sink rim, which is of but slight height.

A further object is to provide a joint between the sink rim and the edge. of the counter top surrounding the opening therein, from which the sink depends, which can be eifectively sealed against water and moisture leakage.

A further object is to provide a joint, which presents the maximum in sanitation, the joint being readily cleanable and being constantly.

maintained without any opening of the joint, which would permit grease and dirt to enter the n A further object is to provide a construction in which a. counter top made of wood and surfaced with a non-water absorbing material can be assembled, so that the wood parts thereof are kept entirely away from the sink and moisture.

Another object is to provide a sink which can be more easily attached to a' counter top and which when attached is a better permanent installation than has heretofore been possible with the usual types of sink constructions.

Another object is to improve upon existing sink rim constructions by providing a means, which effectively seals the joint between a counter top and the sink rim against the entrance of a moisture into the joint.

Still another object is to provide a sink rim construction, which includes a flange to protect the inner wall of the opening in the counter top against the entrance .of moisture especially into the end grain of a counter top made of wood.

With these and other-objects in view, my invention consists in the construction, arrangement and combination of the various parts of my sink and counter top construction, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which:

Figure 3 is a. sectional view similar to the left side of Figure 2, showing a modified construction; and

Figure 4 is a similar view showing still another modified construction.

On the accompanying drawing, I have used the reference character A to indicate generally a sink. The sink A is illustrated as being of enameled sheet metal and is characterized by a novel rim construction, comprising a horizontally, extending raised portion III, a drop portion l2 and an outer, horizontally extending attaching flange ll. The portions l0, l2 and M, of course, extend peripherally around the sink edge. The portion I0 is preferably provided with a groove Hi to receive sealing compound or material iii.

A counter or table top is indicated generally at Band in my preferred form of construction comprises a lower or supporting portion 20 and an upper overlay portion 22. The portion 20 may be formed of four-ply wood, such as bass wood, while the upper portion 22 is formed of a waterproof or non-moisture absorbent sheet, such as Presdwood or linoleum. The two are glued together and their edges may be trimmed with a metal molding 24, secured in .position by screws 26.

A sealing strip or compound is illustrated at 28 to prevent moisture from entering between the molding 24 and the top portion 22.

The flange I4 is provided with spaced perforations adapted for the reception of screws 30, which extend up into the supporting member 20 for thereby supporting the sink A rigidly in position.

The member 20 is provided with an opening 32 somewhat greater in diameter than the flange l2, while the top member 22 is provided with an opening 34 smaller than the opening. 32 and slightly larger than the interior diameter of the sink A at its upper edge. The drop portion I2 is of the same height as the thickness of the member 20,- so that the lower surface of the top member 22 rests upon the flange. i0 and is env top at the point where one stops-and the other begins. v

In Figure .3, I show a sink A formed of enameled cast iron or the like, having an attaching flange Ma. Screws 30a are illustrated for attaching the flange to a wood table top B having an opening 32a therein.

The flange a is provided with a groove i to in which sealing material lid. is positioned.

This construction 'is an improvement on the usual sink, which does not have a groove adapted for the reception oi sealing material, but rather ber, warpingfiof the board can occur without opening the sealed joint, because the mastic or spongerubber expands when the joint. is open and can expand to a considerable percentage of its compressed thickness, whereas when a groove is not provided and putty or white lead is used,

there is no possibility of such expansion to maintaln the joint closed.

In Figure. 4, I show a further improvement over Figure 3', in which an additional flange [2a extends .upwardly from the inner edge of the peripheral flange a to line the inner wall ofthe opening 32a. The sealing material extends upwardly from the groove l6a along the flange l2a, as indicated at lilb to prevent water gettin into the joint between the flange I20 and wall 32a and compensate for any variation injdistance between the flange and the inner wall of the opening.

This construction effectively prevents moisture from soaking horizontally into the edge of the top B which is especially desirable, where the end grain is exposed.

With respect to the seal .at I8, this may be of any suitable yielding materiahwhether caulking,

packing or sealing compound. When a groove is provided for this material, a much more effective seal results, which is impervious to the entrance of moisture to the joint beyond the sealing materlal. I

Some changesmay be made in the construction and arrangement of the various parts or my sink and counter top construction, without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:
